- HORSE HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 413,726, dated October29, 1889.

Application filed November 2, 1888. Serial No. 289,798. (No model.)

' that class of horse hay-rakes known as selfdump rakes). in which thetraction of the Wheels isemployed at the will of the operator to elevatethe teeth and discharge the collected load; and it has for its objectthe improvement in the construction of this class of machines. I Y

The novelty of my invention will be herein set forth, and specificallypointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a rakeembodying my invention, but with the drivers seat and seat-beam removed.Fig. 2' is a side elevation of the same through the dotted line as w ofFig. 1;

tical parts in all the figures.

The frame of the rake may be of the usual onany suitable construction,and is here represented as composed of the thills A, crossgirths B, rearclearer-bar 0, having the cleaner-sti'cks D projecting rearwardlytherefrom,

. center bar E, seat-beam F, and drivers seat G, all firmly united orbolted together. This frame is carried upon the'round metal axle H,which is suitablyjournaled in boxes I, se-

cured to the under side of the thills and bar E at points nearlyhalf-way between the clearer-bar and rear girth. One or both of theusual wheels J may be keyed to the axle to cause its revolution, or (andthis is the preferred construction) both wheels are connected to theaxle by ratchet-and-pawl connectionsto cause the revolution of the axlewhen the machine is advancing or turning in either direction and topermit the axle to remain stationary when the machine is backed, as iswell known in this class of machines.

The rake-head may be of the usual or any suitable construction andpivoted or hinged upon the frame; but I prefer the construction shown,in which I employ three bell-crank arms K, the outer ones of which arepivoted, as at co, between ears 19, secured upon the thills just in rearof the axle, and the middle one similarly pivoted upcn the bar E, withall three pivota[ points concentric and in a line parallel with theaxle. Secured in the upper ends of the two diverging arms of thebellcranks are rods L and M, upon the former of which the tooth-holdersN, carrying the raketeeth 0, are secured, and the latter pass back overthe bar M, which is provided with guide,-

.Staples 0, extending upward and straddling the teeth. Any form oftooth-holder may be employed; but I have provided a simple one (shown inFigs. 8 and 9) consisting of a thim ble N, having a rearwardbase-extension d and side walls a, just far enough apart to receive theend of the tooth, which is curved or ,bent downward and has the bentportion insorted through an aperture fin the base d, as seen in Fig. 9.The tooth thus inserted is secured by a pin or key g, inserted throughthe side walls e just over the straight part of The same letters areused to indicate identhe tooth in rear of the perforation f, and whichserves to lock the tooth in place. The thimbles N are strung and free toturn within the limit of movement of the play of the teeth on the rod Land abut against each other.

P is an ordinary hand-lever secured to the middle bell-crank K, fordumping the rake by hand when so desired, and its lower end may beinserted in a socket formed upon a web connecting the two arms of thebellcrank, as indicated in Figs. 1 and 2.

Keyed or otherwise fastened to the axle H at or near its middle is aratchet Q, which revolves with said axle, and loose upon said axle bythe side of said ratchet is a lifting wheel or drum R, whose peripherypreferably extends over and incloses the ratchet. The front portion ofthe periphery of the drum is grooved to receive and retain a chain h,whose lower end is secured to the drum, as at the lug i, by anadjustable eyebolt j, and whose upper end is secured to the bar L inline with the periphery of the drum in any suitable manner. The rearside of the periphery of the drum has an opening or slot k, in which isconfined the rear projecting end of a sliding dog S, which extendsforward by the side of the drum and is loosely pivoted, as at Z, Figs.5, 6, and 7, to a lever T, whose lower end is pivoted, as at m, to theside of the drum. A spring n is interposed between the hub of the drum Rand the end of the dog, as shown, and serves to hold the latter normallyout of engagement with the ratchet Q. Links 0 connect the upper end ofthe lever T to any suitable treadle p, pivoted, as at q, to a lug 0'upon the rear girth B in such manner that when it is desired to dump therake the driver presses with his foot upon the treadle, and therebydraws forward the lever T and dog S, whose projecting end enters theslot and becomes engaged with the ratchet, as will be readilyunderstood. In this way the drum becomes locked to the revolving axleand partakes of its motion, thereby drawing upon the chain 71. andtilting forward the rake-head and lifting the teeth, as seen in Fig. 4.WVhen the teeth have been sufficiently elevated to discharge thecollected load, a projection upon the lover T comes in contact with aplate .9 or any other suitable trip secured to the bar E, (see Fig. 6,)and is arrested until the slightly-farther forward revolution of thedrum presses it upward and forces the dog S out of engagement with theratchet Q, thereby breaking the lock between the drum and ratchet andpermitting the teeth and rake-head to drop back and reset themselves.The tilting backward of the rake-head reverses the revolution of thedrum and resets it, as will be readily understood. To prevent the drumfrom revolving too far backward under the impetus given it by thefalling of the teeth, I provide two stops, either or both of which maybe employed. The first is a lug t upon the side of the drum, whichstrikes the under side of the plate 5 and arrests the drum, and thesecond is a chain 11, the upper end of which is, secured to the bar Mand the lower end to a lug -v upon the periphery of the drum, but whichalso has another function, to be presently explained.

The remaining feature of my invention is an automatic lock for holdingthe teeth and rake-head locked when the former are down at work, andwhich lock is broken when the drum is to be locked to the ratchet. Itconsists of a spring-projected latch U, confined in a housing V, securedto the bar E just in rear of the rear end of the dog S, in such positionthat when the drum is reset by the falling of the teeth the rear end ofthe dog S forces in and passes below the latch U, which latter isimmediately projected by its spring over said dog, and through themediumof the chain 11/ looks the teeth and rake-head, as will be readilyunderstood. The drawing forward of the dog S, as before explained, toengage it with the ratchet frees it from. the latch U, so that therake-head is free to be tilted, as will be readily understood.

A modification in the construction by which the same advantages of thelocking-bolt are obtained is shown in Fig. 10. Here the lower wall ofthe slot 7c in the lifting wheel or drum is extended back of the dog S,as at 1:, so as to come under and be engaged by the boltU when the teethare down at work. The housing Vhasa lever w, pivoted,as at a, andengaging at its upper end with the bolt U. A supplemental chain orcord 1) extends from the lower end of the lever w forward to the treadle19, or to the links 0 near the treadle, so that pressing upon thetreadle simultaneously retracts the bolt U and draws forward the dog S,the adjustment being such that the bolt U is fully retracted to releasethe lifting-wheel before the dog effects its engagement with theratchet, as will be readily understood.

Having thus fully described my invention, I claim 1. In a horsehay-rake, the combination, with the frame, carrying-wheels, tiltingrakehead mounted on said frame, and revolving axle, of a ratchet fastupon said axle, a liftingwheel loose upon said axle by the side of saidratchet and connected to the tilting rake-head, a locking-dog carriedupon the lifting-wheel, with means for causing the engagement with anddisengagement from the ratchet-wheel, and a locking-bolt mounted on theframe, arranged to engage with said locking-dogwhen the latter isdisengaged from the ratchet-wheel and to be disengaged from thelocking-dog upon the engagement of the latter with the ratchet-wheel,substantially as and for the purpose described.
